Fig. 38 is a detail inner side view of a portion of one of the skein holder bars.

The machine illustrated in the drawings, is particularly adapted for use in forming the embroidery skein shown in Fig. 26. comprises a yarn or thread 2 which is wound in the form of a figure 8 with the coils of the thread arranged side by side. A label 4 is secured about the central portionof the skein, the label extending the major portion of the length of the skein. Previously to applying the label, the portions of the coils extending the length of the the skein. The end 6 of the thud projects loose- This skein 1y a distance beyond the end of the skein so that it may be easily grasped by the fingers of the user to pull the coils from the skein. The other end 8 of the thread projects a lesser distance from the end of the label.

With the skein as thus formed, the figure 8 coils are firmly held together by the long label. By extending the end of the label close to the corresponding end of the skein and arranging both ends of the thread at the other end of the skein, the user. by pulling on the projecting end of the thread, may easily unwind the coils without danger of the loops at the opposite end of the skein snarling or becoming entangled. In case the end 6 of the thread is cut close to the label while in use, the skein may be unwound by means of the other end 8 of the thread.

Thus the user receives the skein with the coils properly arranged throughout, and the skein may be easily and conveniently unwound as it is used without danger of snarling the thread.

In addition to winding skeins and applying the labels thereto, the machine is adapted to pack the skeins in boxes with a predetermined number of skeins in each box.

The thread 2 from which the skeins are formed is delivered to the machine from a suitable thread supply and passes through a thread guide 10, a

tubular shaft l2, a thread guide I3 on the forward or inner end of the shaft, and a thread guide I4 carried by the end of an arm l6 secured on the forward end of said shaft l2 (Fig. 1). From the thread guide l4 the thread passes through a thread guide I8 that is carried by a flier 20.

{The flier 20 and the thread guide carried thereby are moved in the path of a figure 8 so as to cause the thread to be wound upon a frame or holder. This holder comprises two rails or bars 22 having cylindrical heads 24 on their front ends (Fig. 33). The flier 20 winds the thread in a form of a figure 8 over these heads 24 and as each coil is wound rotating arms 26 engage the ends of the coil and slide it forwardly on the holder bars, the front portions of the bars and the heads 24 being provided with clearance slots 28 through which the ends of the arms pass.

The portions of the bars22 adjacent the heads 24 are of smaller diameter than said heads but their outer surfaces are spaced further apart, the rear portions 30 of said surfaces being tapered inwardly flush with the surfaces of the heads.

As each coil is thus slid forwardly on the bars 22 by the arms 26, it engages and slides forwardly the coils previously wound until a predetermined number of coils have been wound about the bars to form a skein. Such formation of the skein takes place at station 32 on the bars. When a skein has thus been wound, fingers 34 engage the upper and lower lengths of the last wound coil and advance the skein along the bars to a station 36. The fingers 34 are arranged in sets spaced along the bars 22 and all moved together longitudinally of the bars.

When the next skein has similarly been wound on the rods, the two skeins are advanced on the bars by the fingers 34, the first skein that is wound being advanced to station 38 and the second skein to station 36. Such advancing of the wound skeins on the bars takes place while the flier 20 continues to wind the thread on the bars, and the skeins are successively advanced on the bars from station 38 to stations 40, 42 and 44.

In order to hold the skeins at the various stations from working rearwardly, the last wound coils of each skein are laid in notches 46 in the skein-holding bars 22, the notches 46 being properly positioned to receive the coils.

When each skein reaches the station 44, knives 48 sever the thread extending between the skeins at the stations 44 and 42, and grippers 50 grip the end of the thread of the skein near the station 42, the other severed end of the thread being permitted to hang loosely from the skein at station 42.

In order to insure the length of thread extending. between the skeins at stations 42 and 44 being in position to be acted upon by the cutters 48 and grippers 50, a locating device 52 which comprises a blade having a pointed or beveled upper end, engages the rear side of the thread and places a portion thereof in proper position to be engaged by the knives and grippers.

The grippers 50 carry the end of the thread held thereby against the rear side of the skein at station 44. When this takes place, devices 54 engage the coils of thread at points spaced from the holder bars, and firmly squeeze the portions of the coils at these points together both laterally and vertically while maintaining the side by side relation of the coils. When this occurs the label 4 is applied tightly about the portion of the skein extending between the two sets of devices 54, and thus serves to hold the portions of the coils enclosed by the label firmly together in side by side relation.

When the label has thus been applied and secured about the skein at station 44, the skein is advanced to station 45. Also, the skein at station 42 is advanced to station 44 and the thread likewise severed and a label applied to the skein.

'From the station 45 the completed skeins are successively slid by fingers 34 off the forward ends of the bars, and upon rods 56. These rods are arranged in alinement with the bars and have their ends received in recesses 58 in the ends of the bars.

As each skein slides on to the rods 56, it pushes the previously wound skeins along with it, until a predetermined number of skeins are thus received in side by side relation on said rods. When this occurs a head 60 (Fig. 27) is moved downwardly over the group or layer of skeins on the rods 56, and a box 62 is moved upwardly in proximity to the under sides of the rods. The head 60 comprises a plate that extends over the tops of the skeins. Depending flanges 64 on the ends 01' the rear edge of the plate have semi-circular clearance notches 66 which, when the head has been moved down, receive the upper portions of the rods 56 at the rear of the skeins. The Plate is provided with both front and rear side depending flanges 68.

Adjacent the rear edge of the head 60 are stripping fingers 10 having their lower ends fitted around the inner portions of the rods 56 and arranged adjacent the front side of the foremost coil of the foremost skein.

When the head 60 thus moves down over the layer of skeins on the rods 56 and a box 62 is moved up into proximity to the underside of said rods, the rods are retracted so as to cause the layers of skeins to be stripped from the rods by the stripping fingers 10. During this stripping operation, the head 60 assists in holding the skeins from piling up on one another and maintains them in side by side relation so as to cause them to be deposited in a layer in the box 62.

This operation of assembling the skeins in a layer on the rods 56 and then depositing them in a box 52, is continued until three or other desired number of layers have thus been deposited in the box one upon the other.

When the desired number of layers have thus been deposited in a box, the box is discharged down a chute I2 and from the machine, and the next box that is to be filled is fed into position beneaththe rods 56.

Each box is supported beneath the rods 56 and is moved vertically toward and from the rods 56 by means of a table I4 which has front and rear upstanding fianges 16 for receiving the box between them. The boxes to be filled are arranged in a magazine I8 and are successively delivered to the table 14.

The mechanisms for performing the several operations above referred to will now be described.

The thread guide I8 of the flier 20 is screwthreaded on the reduced end of a pin 80 which is mounted to turn in a carrier sleeve 82 (Figs. 11, 12 and 13). The pin 80 is held from axial movement in the sleeve 82 by a hub 84 on the guide engaging one end of the sleeve, and a collar 86 secured on the rear end of the pin adjacent the other end of the sleeve, the collar 86 extending into a recess or counter bore in the end of the sleeve.

The thread guide I8 is in the form of a flat plate and its thread guide opening 81, its outlet end centrally located with the axis of the pin 80, and the other end of the opening being normally above said axis.

During the travel of the flier to wind the thread about the skein-holder bars 22, the stretch of thread extending to the thread guide I8 is maintained sufficiently taut to maintain the thread guide substantially vertical (Fig. 12). Such control of the thread is effected by the arm I6 (Fig. 1) which makes two revolutions for each com plete figure 8 movement of the flier 20.

The illustrated machine is provided with novel and improved mechanism for traversing the flier 20 as above described. As shown, this mechanism comprises two intermeshing gears 88 whichare arranged with their axes in a horizontal plane (Figs. 1, 3, 10 and 13). Each gear is formed with oppositely directed miter or spiral teeth with a peripheral groove 90 arranged between the two sets of teeth, Each gear is also provided with a transverse groove 92 in its periphery, a portion of a tooth being omitted where the groove is 10- cated and the center of of the groove being spaced from adjacent teeth a distance corresponding to the distance between the centers of adjacent teeth.

The grooves 92 in the gears 88 are so located that the grooves are brought opposite each other or in registry at the completion of each revolution of the gears.

The carrier sleeve 82 for the flier 20 is adapted to be received in each of the grooves 92, with a centrally located annular rib 94 on the sleeve extending into the groove 90 so as to hold the carrier sleeve from axial movement. v

The ends of the sleeve 82 are provided with laterally directed wedge shaped guiding members 96 which extend over hubs 98 on the sides of each gear. The hubs of the two gears extend through openings in plates I (Fig. the walls I0 I of the openings being spaced from the per phery of the hubs so as to provide guideways for the guiding members 96 of said sleeve 82.

During the rotation of the gears 88 the carrier sleeve 82 is carried in the groove 92 of one of the gears, the sleeve being held in the groove by the guiding members 96 riding in their said guideways. When the grooves 92 reach a position opposite each other, a switching device acts to shift the carrier sleeve into the groove 92 in the other gear. 7

This switching device comprises an arm I02 which is secured on the end of a rock-shaft I04 and is operated through an arm I05 that carries a cam roll I06 engaging in a cam groove I 01 (Figs. 1 and 9). The switch arm I02 has its upper end pointed or beveled as shown.

When the flier 20 carried by one of the gears reaches a position opposite the groove 92 in the other gear, one of the guiding members 96 of the groove 92 in the first gear, said one of the guide members 96 rides on the opposite side of the beveled end of the switch arm I02 to shift the fiier into the groove in said first gear.

It will be apparent that Withthis construction the filer travels at a constant speed in the path of a figure 8, the fiier being alternately carried by first one gear and then the other. The flier is capable of high speed operation smoothly and uniformly, and with a minimum amount of wear on the parts.

Each of the gears 88 is secured on a shaft I08 which is journaled in hearings in a gear casing IIO (Figs. 1, 3 and 10). The drive for the gears 88, comprises a pinion II2 secured on one of the shafts I08 which is engaged by a gear II3 on a shaft II4, which shaft also carries a pinion II?) that is engaged by a gear I I6 secured on a shaf t I". A pinion II8 on the latter shaft is engaged by a gear I24 that is carried by the main cam shaft I22 of the machine. This camshaft is driven through the gear I24 (Fig. 5) which is engaged by a pinion I25 on a shaft I26 that carries a gear I21 driven by a pinion I20 on the main drive shaft I30 of the machine.

The shaft II4 (Fig. 1) carries a sprocket wheel I32 in the side of which the cam groove I0! for operating the switch arm I02 is formed. The sprocket wheel I32 (Figs. 1 and 9) through a sprocket chain I34 drivesa sprocket wheel I35 on the end of the tubular shaft I2 that carries the yarn compensating or equalizing arm I8.

Each of the pair of thread positioning arms 26 (Figs. 3 and 5) projects from a collar I36 which is secured on the upper end of a vertical shaft I3'I. The two shafts I3! are driven to rotate the arms as above described, through miter gears I38 which connect the lower ends of the shafts with a shaft I39. The shaft I39 carries a bevel gear I40 which is operatively engaged by a gear I42 on one end .of a short shaft I43 (Figs. 1 and 10).v The shaft I43 is driven through a gear I45 on the other end thereof that is engaged by the gear II3 on the shaft II4.

Inasmuch as the skeins pass the full length o the bars 22 (Figs. 1, 3 and 5),n'ieans must be provided for supporting those bars in such a way as not to interfere with the passage of the skeins,

As shown, each bar is supported by two spaced sets of semi-circular disks I46 which are adapted to fit into curved slots I41 in the top and bottom surfaces of each bar (Figs. 3, 6. 7. 8 and 33). Each set of disks I45 comprises two pairs of disks, Fig. 8, the disks of each pair being adapted to respectively engage in upper and lower slots so operated that when one pair is in engagement in the slots I41, the disks of the otherpair of the set are out of engagement with the slots, the corresponding pairs of disks of the two bars being moved simultaneously into and out of engagement with the slots. The disks I46 are moved into and out of engagement with the slots in the bars by rotation thereof in opposite directions 180 degrees. I

The operation of the disks I46 is so timed with the skein feeding fingers 34 that as a skein approaches the front pairs of disks of corresponding sets, these disks are turned (viewing Fig. 8), so as to move them out of engagement with the slots and away from the rods to permit the skein to pass beneath the disks. Simultaneously with this movement of the front pairs of disks, the rear pairs of disks are moved into engagement with their associated slots. Thus as a skein approaches the front pairs of disks, the skein is permitted to pass by said disks, and as the skein approaches the rear pairs of disks, those disks are swung away from the bars so as to permit the skeins to pass by them, the bars then being sup-' ported by the.front pairs of disks.

The disks I46 are carried by the inner ends of shafts I48 which are journaled in bearings in supporting brackets I49. The outer ends of the shafts I48 carry pinions I50 which are engaged by teeth on the top and bottom sides of racks I52,'each rack operating all of the disks I46 associated with each skein holder bar 22.

The two racks I52 are reciprocated to operate the disks I46 as above described by means of arms I54, the upper ends of which are bifurcated to operatively engage pins I55 on the racks. The arms I54 are secured on a shaft I56 so as to cause them to move together. The hub on one of the arms I54 (Figs. 6 and '7) is provided with an arm I58 which is connected by a link I60 (Figs. 1 and 7) with a lever I6I that carries a cam roll I62 engaging in a groove in a cam I63 on the main cam shaft I22.

The fingers 34 for advancing the skeins along the skein holder bars 22 are formed on arms I64. There are four arms I64, the series of upper fingers 34 associated with a bar 22 being formed on one of the arms and the series of lower fingers associated with a bar is formed on another arm. Each of the arms I64 is secured on a rock shaft I66 that is mounted to turn and slide longitudinally in bearings in horizontal transverse frame members I68 (Fig. 3).

The four rock shafts I66 are adapted to be turned to move thefingers into and out of position adjacent the rear sides of the skeins, by means of segmental pinions I (Fig. 6) which are connected with the shafts by keys I12 that cause the shafts to turn with the pinions but permit the shafts to be moved longitudinally through the pinions.

The pinions I10 associated with the upper shafts I66 are in intermeshing engagement, and the pinions I10 associated with the lower shafts I66 are also in intermeshing engagement and means is provided for oscillating one of the pininner ends, and the lower arm I18 is pivotally connected to the upper end of a rod I82 which is mounted to Slide vertically. This rod I82 carries a cam roll I83 that engages a groove in the side of a cam disk I84 carried by the main cam shaft I22.

The fingers 34 are moved longitudinally in opposite directions, as above described, by means of a block or cross-bar I86 (Figs. 3 and 7) secured to each pair of shafts I 66 and operated through a pin and slot connection with the end of an arm I 88, the two arms I88 being secured on a vertical rock shaft I89. the rock shaft I89 carries an arm I90 which is connected by a link I92 with the end of an arm I 93 that carries a cam roll I94 engaging a groove in a cam I95 on the main cam shaft I22.

The thread positioning device 52 for positioning the thread in the path of the thread cutting and gripping devices 48 and 50, is formed on the end of an arm I96 secured on a shaft I91 mounted in bearings in the machine frame (Figs. 18 and 33), The shaft I91 is actuated to raise and lower the device 52 by means of an arm I98 secured thereon which is connected by a link I99 with an arm 200 secured on a shaft 20I (Fig. 1). shaft is actuated through an arm 202 secured thereon which is connected through a link 203 with a lever 204 that carries a cam roll 205 engaging in a cam groove in a cam 206 on the main cam shaft I22 (Fig. 1).

The thread severing knives 48 are secured on the ends of the upper arms of levers 208 that are pivoted on a pin 209 which is secured in a bracket 2I0 (Figs. 14 to 17). The twoarms are pressed toward each other by means of a spring 2 I 2 coiled about the pin 209 and interposed between the hub of one of the knives and a washerand nut 2I4 screw-threaded on the pin 209, the knives being held on the pin 209 by the head 2I5 on the end of the pin. The lower arms of the levers 208 are inclined so as to cross each other and extend between studs or pins 2I6 on a plate 2I1.

The thread grippers 50 are formed on the upper ends of spring arms 2I8, the lower ends of. which are secured to arms 2I9 which are pivotally mounted at 220 on the lower arms of the knife levers 208. Thelgrippers are pressed toward each other by means of a coiled spring 222 connecting the arms 2I9, the inward movement of the grippers being limited by the engagement of the upper end portions thereof with the outer sides of the knives.

The arms 2I9 are provided with depending lugs 224 carrying adjusting screws 225 that bear against the outer sides of the lower arms of the knife-carrying levers 208.

The bracket member 2I0 which carries the knives 48 and the grippers 50, is formed on a block 226 which is mounted to slide horizontally on a bracket arm 228. The bracket plate 2I1 is mounted to slide horizontally with the block 226 in a guideway 230 in a fixed plate 23I.

The bracket arm 228 is formed on a casting 234 which is mounted to slide vertically, carrying the block 226 therewith on a vertical shaft 236 and a pin 238, the latter being secured to the base plate 232, and the block 226 being connected with the plate 2I1 through a guide-way 231 which permits the block to move vertically with relation to the plate 2I1.

With this construction it will be apparent that by sliding the block 226 on the bracket arm 228,

- the knives 48 and gripper 50 may be moved ion- The lower end of The-
